Occupational exposure to mechanical vibration: the Italian vibration database for risk assessment.

Abstract

The Italian vibration database is presented. It is hosted by a web server at the National Institute of Occupational Prevention and Safety (ISPESL) in Rome, Italy (http: / /www.ispesl.it/vibrationdatabase). It supports in risk assessment employers who have to comply with Legislative Decree 187/05, now replaced by Legislative Decree 81/08, which transposes into law Vibration Directive 2002/44/EC. The database currently contains measurements and EC-declared values from over 980 hand-held power tools (such as pneumatic and electric hammers, chainsaws, grinders, drills, sanders and saws) and from over 420 vehicles (such as buses, forklifts and wheel tractors). The database is continuously updated as soon as new experimental and declared data are acquired.

The Italian vibration database is presented. It is hosted by a web server at the National Institute of
Occupational Prevention and Safety (ISPESL) in Rome, Italy (http://www.ispesl.it/vibrationdatabase). It
supports in risk assessment employers who have to comply with Legislative Decree 187/05, now replaced by
Legislative Decree 81/08, which transposes into law Vibration Directive 2002/44/EC. The database currently
contains measurements and EC-declared values from over 980 hand-held power tools (such as pneumatic and

1. INTRODUCTION
Despite a decline in the proportion of the
workforce employed in traditional, physically
demanding sectors such as manufacturing,
construction, agriculture and mining, some
physical risks such as mechanical vibration and
noise are still prevalent. It has been estimated
that a total of ~24% of European workers are
exposed to mechanical vibration, and the trend
has shown a slight increase since 1990 [1]. About
26% of Italian workers, i.e., over 5 million people,
are exposed to potentially harmful mechanical
vibration at the workplace; 11% are exposed all
the working time, 8% at least three quarters of the
time and 7% at least one quarter of the time.
There is strong epidemiological evidence of
a relationship between occupational exposure
to hand–arm vibration (HAV) and a number
of health effects and injuries referred to as the

JOSE 2008, Vol. 14, No. 4
hand–arm vibration syndrome (HAVS). There is
also epidemiological evidence of a relationship
between occupational exposure to whole–body
vibration (WBV) and a number of health effects
and injuries of the spine. Despite this evidence, the
Italian Workers’ Compensation Authority (INAIL)
until recently recognised and compensated only
for vascular and musculoskeletal disorders of the
hand–arm system and the carpal tunnel syndrome.
At present mechanical vibration is the fifth most
common occupational disease compensated for in
Italy.
After European Union Directive 2002/44/EC [2]
was issued, the Italian government implemented
it with Legislative Decree 187/05, the first Italian
regulation specifically dedicated to occupational
exposure to mechanical vibration. It came fully into
force on January 1, 2006. It has now been replaced
by Legislative Decree 81/08 [3]. According to this
law, employers have to implement a programme
of prevention and reduction measures in the
workplace. In particular, they need to assess the
level of mechanical vibration to which workers are
exposed and, if necessary, measure that level with
special apparatus and appropriate methodologies.
On the basis of that risk assessment, the employer
should determine what measures to take according
to legal obligations: worker information and
training, health surveillance and/or provisions
aimed at avoiding or reducing exposure.
Even though mechanical vibration is a
traditional physical risk factor, in Italy there
are no competent services or technicians able
to assess and measure the level of mechanical
vibration to which workers are exposed. Hence,
Legislative Decree 81/08 allows employers to
use as sources of information on the magnitude
of vibration manufacturers’ emission data and
national databases established by the National
Institute of Occupational Prevention and Safety
(ISPESL) and the Regions. At present, there is
only the ISPESL database, which has become the
centralised Italian database to support Legislative
Decree 81/08 for risk assessment purposes.
The idea of this database originated during the
Vibration Injury Network research project (1999–
2001), supported by the European Commission
under the BIOMED 2 programme. Two Italian
partners were involved: ISPESL and the Local
Health Service of Siena. The format of this
database fulfils the following requirements:
•? data are presented in a clear, understandable
and useful way;
•? the database is easily accessible by a large
number of users (in the first year ~200 000
visitors accessed the database);
•? measurement data pass through quality control
before insertion;
•? data are based on measurements conducted
in accordance with European Committee
for Standardization (CEN) or International
Organization for Standardization
standards;
•? new data inserted in the database are quickly
accessible for users;
•? corrections and additions are easy to introduce;
•? the database is easy to manage and maintain.
(ISO)
The aim of the database is also to advise
employers on the choice and purchase of work
equipment of appropriate design producing the
least possible vibration transmitted to the hand–
arm system and to the whole body, in compliance
with Article 5 of European Directive 2002/44/EC
[2]. In fact this article, among the technical and/
or organisational measures intended to reduce
to a minimum exposure to mechanical vibration
and the attendant risks, states that the employer
takes into account in particular “the choice of
appropriate work equipment of appropriate
ergonomic design and, taking account of the
work to be done, producing the least possible
vibration”.
2. DATABASE CONTENT
The database currently contains measured data
(collected by ISPESL and the Local Health Service
of Siena) and EC-declared values relative to over
980 hand-held power tools (such as pneumatic
and electric hammers, chainsaws, grinders, drills,
sanders and saws) and from over 420 vehicles
(such as buses, forklifts and wheel tractors).
After loading the homepage (Figure 1), the reader
is directed to the User Guide to the Vibration
Database, which has to be read and accepted.

The guide helps the user to use the database
properly; instructions should be followed carefully
as assessment of exposure to vibration with
databases is a delicate and difficult task for which
measurement remains the reference method.
The guide also instructs the user how to properly
manage manufacturers’ vibration emission values
declared according to Machinery Directive
98/37/EC [4]. They are reported in instruction
handbooks of hand-held power tools and hand-
guided machines or other publications; they are
used to determine daily exposure A(8) according
to the recommendations in Technical Report CEN/
TR 15350:2006 [5]. In fact, for some families

of machines the total value of vibration ahv can
be estimated with a correction factor c to be
multiplied by the declared vibration data.
At the end, the guide directs the user to
effective field reductions of antivibration gloves,
when they are used as personal protective
equipment to reduce exposure to hand–arm
vibration. In fact, those gloves, which have to be
CE marked and certified according to Standard
No. EN ISO 10819:1996 [6], show values of
effective reduction measured in the field ranging
from a minimum of under 10% for percussion
tools to a maximum of 60% for some rotatory
tools. At that point the reader is allowed to access
the database, and a tool bar menu can be activated
(Figure 2).
If, e.g., the HAV button is picked, readers
enter a search menu where the first item
(Search) allows them to search the tool database
with a number of filters that can be activated.
The second item (Complete list) allows them
to browse through the tool list page by page
(Figure 3). Each page reports a list of tools
identified by tool category, constructor and model
and the EC-declared value; the maximum value
measured in the field is reported. When a tool has
been found, a complete data sheet is available
by clicking on the instrument’s active link; the
